On the Security of a Self-healing Group Key Distribution Scheme

Yandong Zheng, Hua Guo

Abstract: Recently, in Journal of Security and Communication Networks (5(12):1363-1374, DOI: 10.1002/sec.429), Wang et al. proposed a group key distribution scheme with self-healing property for wireless networks in which resource is constrained. They claimed that their key distribution scheme satisfies forward security, backward security and can resist collusion attack. Unfortunately, we found some security flaws in their scheme. In this paper, we present a method to attack this scheme. The attack illustrates that this scheme does not satisfy forward security, which also directly breaks the collusion resistance capability.

Category / Keywords: cryptographic protocols / Cryptanalysis, forward security, collusion resistance, self-healing key distribution.
